Cavity ties are unseen components that connect the cavity wall’s internal and external leaves. The ties are attached to the cavity wall during construction, with their ends bedded into the mortar bed at regular intervals. The wall ties span the cavity, connecting the inner leaf with the weight to the outer leaf.
Cavity ties provide stability to the outer leaf by anchoring it to the wall. Additionally, they are designed to accommodate minor movements caused by temperature swings and prevent water transfer from the outside.
Failure of wall ties can be extremely costly if not recognised and addressed promptly. Wall tie failure can result in the entire collapse of an outer leaf wall in the most extreme circumstances. The more corroded or damaged the wall ties get, the more difficult they will replace. Therefore, it is prudent to take preventive actions against the causes of wall tie damage and cracks.
The most common indicator of cavity tie failure is the formation of horizontal fractures in the exterior wall. If you suspect you have issues with your cavity ties, BrickFix Remedies can carry out an inspection to determine their condition and advise accordingly, including an obligation-free quote for wall tie replacement as needed.
If the cracks in your masonry wall are not due to wall tie failure, you may wish to explore brick stitching (also known as crack stitching) to repair vertical and stepped gaps. Before undertaking this sort of work however, it is essential to get an expert appraisal from a qualified structural engineer. If the cracks are minimal and limited to one area, it is very likely that brick stitching will be the solution of choice.
BrickFix Remedies can provide professional brick stitching / crack stitching services once an engineer’s report has recommended this as the best course of action.
